DENTAL APPLIANCE.

SPECIFICATION forming part of Letters Patent No. 520,357, dated May 22,1894.

pplic o fi December 11, 1893. Serial No. 493,397. (No model.)

To all whom it may concern.-

l 3e it known that I, ZELOPHEARD HAND, a c tizen of the United States,residing at Millville, in the county of Cumberland and State of NewJersey, have invented certain new and useful Improvements in DentalAppliances; and I do hereby declare the following to be a full, clear,and exact description of the inven-,

tion, such as will enable others skilled in the art to which itappertains to make and use the same, reference being had to theaccompanymg drawing, and to the letters of reference marked thereon,which forms a part of this specification.

The invention relates to an improvement in dental tools and has for itsobject the construotion of an appliance to be used in filling distal,mesial, palatine or other surfaces of the teeth by aid of dental mirror,or otherwise, which mirror reflects the light into the cavity or enablesthe cavity to be easily seen by the reflection in the glass.

With these ends in View I have designed the present invention, thedetails of which will be more fully set forth and pointed out in theclaims.

In the accompanying drawing the figure represents my device attached toa tooth.

Like letters of reference indicate like parts wherever they occur. 1

In the drawingA representsa clamp of any sultable material which may besecurely held 1n place on atooth selected for attachment of appliance bya thumb-screw F. This clamp 1s composed of any suitable material such assteel and may or may not be padded, so as to prevent injury to the toothto which it is attached. The jaws a, a, do not preferably entirelysurround the tooth. The jaws a, a, are long enough to get a firm hold onthe tooth, and hold the remainder of the mechanism. The mirror E is heldby a jointed rod, so jointed as to give a great variety of movements tothe mirror, and is composed of the several bars or sections, B, C and D,so attached as to permit any desired movement. The bar B is swiveled orhas a ball and socket joint, in clamp A which may be of any suitableshape. The said bar is held by a set screw G in any desired position.The bar 0 has an elongated slot for the lengthening or shortening ofsaid bar, and is securely held in the proper place with relation to barB by a screw H. The bars B and O are preferably flattened at one end andcylindrical at the other, and the bar 0 is drilled to receive the rod Dwhich construction permits of the rotation of mirror E, at any angledesirable. The bar or rod D is held securely by a screw 1. The outer endof rod D is flattened and split so as to form a clamp in which thehandle of the dental mirror E is grasped. The dental-mirror is firmlyheld by bar D at any desired point by tightening set-screw .I.

By the employment of this device wherein the mouth mirror is securelyheld by said appliance, the operator can readily adjust the apparatus sono movement of the head of the patient will destroy the focus, anddiscomfort to the wearer is reduced to a minimum. The operation isobvious. The operator selects the proper tooth best suited to hold theclamp and the jointed arm attached thereto, and then adjusts the severalsections thereof, and then locks them in the desired position.

The movements of the device are so varied that any position can beeasily secured in filling cavities of the teeth or treating diseases ofthe throat and mouth.

I am aware that prior to my invention dental appliances have been madewith mirror reflection by attachment in and outside of the mouth, and Ido not claim the same broadly, but

What I do claim as my invention, and desire to secure by Letters Patent,is-

1. In a dental apparatus, a clamp forming part of said apparatus,adapted to grasp any tooth, having at one end a ball and socket joint, ajointed arm, having one end adapted to fit said socket, and a set-screwadapted to lock said arm, a dental mirror at the outer end of saidjointed arm, a clamp adapted to receive and hold the handle of saidmirror in the desired position, substantially as described.

2. In a dental apparatus, a clamp forming part of said apparatus havinggripping jaws adapted to grasp any tooth, a jointed arm composed ofextensible sections, united to said clamp by a ball and socket joint insuch a manner as to permit of universal movement, set screws forsecuring the several secthe desired position in respect to each other,tions in the desired position in respect to a clamp upon the outer endof sa d arm, and each other, and a mirror or reflector carried a mirroror reflector secured by clamp, sub- V by said jointed arm, substantiallyas de- I stantially as described. 5
